Abstract

L'invention concerne des procédés, systèmes et appareils destinés à aider à la gestion du retour d'huile, par exemple dans un système de réfrigération d'un système HVAC. Un mélange réfrigérant/huile peut être dirigé hors de l'évaporateur dans un échangeur de chaleur de retour d'huile, conçu pour aider à vaporiser une partie du réfrigérant du mélange réfrigérant/huile. De la vapeur de réfrigérant de surchauffe peut être dirigée depuis un condensateur dans l'échangeur de chaleur de retour d'huile, sous forme d'énergie thermique, afin de vaporiser la partie de réfrigérant dans le mélange réfrigérant/huile. L'échangeur de chaleur de retour d'huile peut être positionné plus bas que l'évaporateur, de sorte que la gravité puisse aider le mélange réfrigérant/huile à s'écouler dans l'échangeur de chaleur de retour d'huile.
